To au whom it may concern e it'known that I, SIGMUND ScHiFFha subject ofthe King of Hungary, residing 1n New York city, county and State of New York, have invented cert-ain newand useful Improvements in Neck-Roll Apparatus for Bottle-Making, of which the following is a specification.

My- 'nventlonis aneck roll apparatus for forming and .finishing bottleneck heads and especiall ytheir bores. It vis especially designed or use in bottle machines; whose output will be considerably increased in number and cheape'ned by its use.

rThe .particular apparatus illustrated is designed to form and finish bottle neck heads for the use of the capillary valve disclosed in my vco-pending application, `Serial No. 749086, and to be used inbottle machines which make bottles in molds, from tankl glass j In the accompanyin drawings all thesections are axial except' .igures 6 and-7.

F ig. 1 is-a general section, Fig. 2 .an en-- larged section of rthe principal .revolvingV members, Fig. 3 a section of thevroller, thel thimble, audits charge *of glass'prior to rolling, and Fig. 4 a section of the `rolled and finished neck head. The remaining fig- 30. i

ures illustrate the eccentric displacement of lthe roller and .means to accomplish the same, Fig. 5 beinga diagram, Fig. 6 a plan (with the driving shaft in section) showing the "eccentric asl locating the roller axially, and

Fig. 7 a corresponding view when its eccentricity is maximum.` The plunger is-shown in the same position in 3, 4, (3 and 7.

' My apparatus can be adapted to any method of, or machine for, making bottles, as for instance, United States Patent No. 766,768, issued to M. J. Owens, August 2, 1904. The drawings illustrate only one arm Aa of the revolving head frame,'the adapter b,-.(which is theymember precisely oper-'ably locating my roll) and the neck mold 0,-f-o`f amachine of knowntype which gathers the viscous glass from a revolving tank, by vacuum, into blank molds `(not shownl and thimbles d, cuts ofi' thegla'ss with a knife. forms the neck-heads, substituting finishing molds yfor the -vblank molds, and blows, finishes and delivers the bottles. Such a bottle 1 machine .has parts not necessaryr to illus trate, but whose functions should be understood, such as means to cause vacuum and bers to manipulate the head frame and, with it, the charged molds and the bottles, during their manufacture. Further reference to the bottle machine is unnecessary except to state that the motive shaft M of my apparatus is suitably geared to and intermittently driven from transmission members thereof (by toothed gearing) and that I substitute a specially designed plunger 1, having 'a revolving head or mushroom, 1, for the plunger now in use, like which it is periodically lifted out of the way of and replaced by the blower slide; no change inthe other usual bottle machine design being necessary.

. It must be understood that the adapter b, the neck mold @and the thimble d must be special to the particular kind and finish of bottle to be made; and that suction passages e are formed in the adapter b, arm a and l neck-mold c, through whichtheblank mold v and the bore of the thimble d may communicate with the vacuum apparatus of the bottle machine, for the purpose of gathering glass.

I mount my apparatus coaxial with the bottle, the thimble d and the adapterb, on

.thev plunger-reciprocating members o'fl the vsupply compressed air, and machine mem-A bottle machine by means cf a tubular stock 2 provided with medial and vouter bearings 2O and 21 for the primary shaft 10 and a bearing formed in an arm 22, for`themotive shaft M, which is rendered flexible by a universal joint m. Bevel gears,".(11, connect the motive and primary shafts,'M and v10; and onthe inward end of the'latter I fix a clutch member, preferably a disklt in Whose l Y ing suction channels 1 which connect said recess lc with the thimble d andthe mold, and containing an eccentric bearing 1'. The forming and finishing roll 4 is made with conformations corresponding with tlao t0. be rolled into the bottle neck; in this case 'with grooves 40 which form contracted rings and their capillary surfaces' and 41 which forms a valveseat. When idle it is axis A of thebo'ttle, which is the general work-axis of the apparatus. In the bearing 1 is an eccentric o and thereon, eccentric thereto byV an eccentricity equal to that of a the bore 1t of the mushroom 1, a tubular driving shaft 5-and.a hollow 'roll shaft 51, which is stepped to secure maximum strength, terminates in a teat 52 and isaxially tapped for a screw 53 which holds the roll 4 on -the shaft 51. As -hereinafter explained, 'I have foundv in actual manufacture that the .roll4 must be operative some-v what within the bottle necks in order `to make them perfect; and I therefore space the roll 4. from the mushroom stem 1l by a hollow former, 1K,v driven into .a socketin said stem co-axial with thebottle, the* bottle otherwise un'yielding.`

mold and the adapter, -andwhose bore gives clearance for the roll shaft 51. The driving-shaft 'terminates in a dog 54 provided with an interrupted, pai-aneisided' tooth 55 lwhich engages one of the grooves 13 inthe clutch head 12 ofthe driving shaft 10, to drive the apparatus by contact surfacesample to secure durability and whose 'axis is perpendicular to the axis of eccentricity X of the eccentricf, so thatwhen it shifts the roll 4 said tooth can slide in said groove torrender the engagement flexible with respect to lsaid motion while I provide between the stock 2 and the revolving parts (the mushrooms, eccentric and roller) a connection whichpermits'them to be readily removed and reassembled and which comprises, loose on the driving shaft.

`50 and adjacent to its terminal disk 54, a collar, 56, having in its face a groove 57;v

and on the stock 2 a socket 23 and mounted therein `a manuallyretractable pin 24, normaliy advanced by a spring 25 and engaged with the groove 57.

Adjacent to lthe'collar' 56 I pin to the.- shaft 50 a disk 58 having a shift `arm 5 for shifti g the'eccentric 5 and displacing the roll flund betweenthe disk 58 and the adjacent face of the "mushroom 1a I interpose a roller or ball thrust bearingGO; and* in some cases I mayL interpose `a lilrebearin between the end oi'ftlie stockJQfandthe dis `58. On the mushroom l, I form a tubular'. stump 1hv in whicli jtlfeend of the stoclt 2 makes a loose fit-*to complete the housing of the running "parts,A which contains'the disk V58 and rollerfbearing 60 andfwh'ose wall is 'slotted to fi'in`two vstops land l `which limit tliumotiorifof the shift arm: 5 and the displacement o'fthev roller 4. o

To graduate the rolling and automatically .more or less unbalanced atmospheric return the eccentric 5 and roll 4 to their neutral, normal position`A after rolling is completed,`so that the rollfcan'be withdrawn .from the finished bottle neck, I connect the eccentric 5 and `mushroom 1 by a spring 59 70 illustrated as coiled springhooked at one end to the arm 5*l and having a graduating connection with the mushroom illustrated as a'tang on the spring anda"properly-spaced series of holes, 1', in the mushroom, into 75 one or other of which the tang of the spring 59 is hooked. v

The operation of my roll is greatly improved .by properly adjusting the effort of the spring 59 to the riction'al resistance t9 80 rotation of the mushroom 1 and the resistance of the viscous glass in the'thimble d to the displacement of the roll. The latter is a natural variable, increasing with the cooling of theglass; and vtheform'er is '85 generally a variable, in bottle machines, because the bottle machine members which reciprocate thev plunger 1 are 'Y generally" spring-cushioned and so designed, actuated and controllable` that theV plunger is', 90 brought without shock into contact 'with the adapter and subsequently Apressed 'against it with a graduated pressure, which i'sreadil 1 controllable.- Further, in machines which gather glass by suction, for which -iny appaf 95 ratusis especially designed, just before and during the initiation of rolling, the mush` room ',1 ispressed againstthe adapter' by ressure, due to the high vacuum between tliem, 1`0 0 whichis readily-controllableby parts essen- I tial'to the operation of 'the bottle machine.

VIn order that the effort of the sprin 59 may be adjusted with precision to thea ove 'described-unavoidable resistances, all other 105 resistances should be, as nearly aspossible, Y

eliminated, and to that end I introduceithe ball bearing or bearings 60.'

If the spring 59 bel Weak relativelyto the rcsistances, it does not graduate the eccen- 110- tric displacement of the roll, but merely returns it to coaxiality after rollingl is completed: 'hcn power isapplied the trans- .mission instantly swings-the eccentric arm i.

5a from the rest stop 1' to the dri'ving'stop 1*' 115 displaces the roll sc cantwise and initiates maximum rolling; and at the end of "the cycle, when the power is suspended, the Y spring' returns the eccentric and roll to ,coaxiality. This mode' of operation is lsuitable 120 for some kinds'of bottles. But if the spring4 59 benice-.ly 'adjusted relatively to the resist- 4ance.' wlicnpou-efr is applied the arm 5sl gradu'zitf-dly strains 'the spring, thespring in if tftesfankl accelerates thel rotation of.'vthc 12 n''ushrooinimd thc.- roll 4 is displaced in a j Spital' untilthe arm 5 contacts with 'thel dri-vingshoulder l after which the. ecccnv tri'c and' mushroom revolve as one piece with tile/froll 4 at its maximum eccentricity; and 13:'

at the end of the cycle, when power is suspended, the spring returns the roll to coaxiality. Care must be taken to adjust the spring so that the arm 5 will, without risk of. failure. contact with the driving stop 1*' ands the roll l will be fully displaced, because otherwise the bottle neck bores would be too small and the roll might not be removable therefrom.

To cool the roll 1, 1 provide a cooling system comprising an aperture in the wall of the stock connecting its bore with an air supply system, of the bottle machine: suitable air channels 27, where necessary, for the flow of air from the stock bore into the bores of the driving shaft 50; a reducing tube 5t connec ing the bore of the eccentric 5 with the extremity of the bore in the roller shaft 51 and forming therein an annular cooling Chamber 5 which discharges into free air through'a passage 5d bored in the eccentric.

My apparatus operates thusly: The assembled mushroom 1, eccentric 5 and roll 4 can be` removed from the stock Z (when the latter is lifted) after pulling out the springpini 24. The eccentric and its belongings can be sepanated from the mushroom after removing the screw 53 and roll 4. The speed at which the roll 4 is eccentrically displaced ,and rolling initiated can be graduated by adjusting the tang of the regulating spring 59 into the suitable hole 1m inthe mushroom. Normally the spring 59 positions the shift arm 5 of the eccentric against the rest stop 1i (Fig. 6) and the eccentric 5 so that the Shafts 50 and 51 and roller 4 are coaxial with the bottle machine and bottle molds. that is to say, on the line F-A.-X, Fig. 5. While so positioned the glass is gathered, and immediately thereafter the motive sha-ft M begins to be revolved (by the aforesaid connection) and to drive the apparatus. The plunger 1 being pressed upon the adapter b by the operation of bottle-machine parts (not illustrated) its friction holds it back and causes the primary and driving shaftsl() and 5() to begin to turn the eccentric 5 in the eccentric bearing 1t of the mushroom la,` strain the spring 59, and thereby graduate the shifting of thel eccentric. the displacement of the roll -l and the initiation of r'ming. After the eccentric arm 5 has been .fully shifted. to contact with the driver stop l, the eccentric mushroom and former 1g revolve as one piece, and the roll elrevolves with them and the rolling effeet is maximum. the axis of eccentricity X and axis of the shafts 50 and 51 and rolleri havingbeen shifted from the line l `-A-X (Fig. 5) to that FE-5X and the shaftand-roller axis from A to E.

The freshly gathered glass usually com pletely fills the annular space between the rollers 4 and 1g and the wall of the thimble d (saw` im" the air which adheresthereto and accidental small air bubbles) as shown in Fig. 3. As rolling is initiated the roll y4 is shifted across the extremity of the former l". to its final position (Figs. 4. 5 and T). The glass is rolled into all cavities and bubble-holes and perfectly fills out the neck-head. even if the thiinble be not perfectly charged. such air as there may be is driven into the space in which the roll works. and. expanding therein. downwardly enlarges said space (Fig. Vl) which is due mainly to the sagging of the glass charge when the knife retires from under the blank mold: the surplus glass is extruded into the blank mold; and the neck head is rolled. finished and sulliciently cooled and hardened. solid and perfect.

The above described operations are done in a fraction of a second. In bottle machines of the type referred to. they are done during the small angular movement of the arm a, beginning substantiallv at the completion of glass-gathering and terminating substantially as the knife completes its function and the plunger begins to lift out of the way of the blower slide. After the bottleI necks or it may be. neck heads are rolled as aforesaid, the bottles are blown in the usual manner.

In practical manufacture, l find that glass cools and hardens so rapidly in the nozzle and its extremity that a roll which (like my roll 4) does any considerably amount of work, must be located a considerable distance within the neck head where the glass keeps its heat better, as in the illustrations, and that attempts to extend the roll to and roll the extremity and tip of the nozzle fail because the quickly setting glass adheres to the top of the roll, and not only are the noz- Zles spoiled but also the rolls, whereas a former like that 1, rotated on the bottle axis. and doing no more rolling than is due to the tremor of the apparatus, operates satisfactorily' and, in connection with the roll l. reliably produces a perfect bottle. provided that the surface of the former lg be made a truncated cone merging into a fillet. 1S. which. during the work, merges substantially into thc head-conformation of thc thimble d. l find that a truly cylindrical surface in the former le' of a fiat annulus thereon extending over the end of the bottlc nozzle. tears the glass and spoils the work.
